He was appointed manager of Argyle on 1 October 1983. However, his managerial career was short-lived, owing to his lack of success in the league, he was dismissed on 19 November 1984.
In his 60-game stint as manager he won 17 games, lost 27 and drew 16. The highlight, for which he is most renowned, was leading Argyle to an FA Cup semi-final. A defeat to Watford meant that Argyle did not become the first team from the Third Division to reach the final.
He returned to Exeter City as coach and then caretaker manager before moving into management in local Non-League football.
